i put an undertail on with integrated LED stop/turn signals and i put front flush mount LEDSwith 18 bulbs in each front signal. i hooked everything up correctly. now when i hit my turn signal not only do they flash fast but all 4 signals flash at the same time. what should i do?!

 

They flash fast because LED's have very little electrical resistance. You need either the inline resisters, or there is a module that you can hard wire into your bike. Both do the same thing. (add more resistance)

I would assume the reason both sides are flashing at the same time is because you wired the wrong leads together. Double check your wiring. If you are not sure which wires do what on your bike, use a test light to determine. And for the undertail LED's, just use jumper wires from your battery posts to test each lead.

 

hit them with a big hammer, thell slow the hell down and stop blinking

But you will give it a mean streetfighter look! lol

 

^^^^ i'm pretty sure i wired them in correctly ... there were 2 yellows and 2 blacks. obvious black is ground so i wired them to the black lead off the bike .. right?

 

You should still test your LED's with jumpers, and use a test light on the bike's wires. Otherwise you're not going to find your problem. That's just what I'd do.

Yes, black is generally ground.

 

black isn't always the ground wire on the 7. they only way the all flash at once is if they are wired together. take a volt meter to see which wiresarethe power wires.
